Versuchsvorschrift

To 3-(4-(7-chloroimidazo[1,2-c]pyrimidin-5-yl)-1H-pyrazol-1-yl)-3-cyclopropyl-propanenitrile (Preparation M; 50 mg, 0.16 mmol) in dioxane (5 mL) was added K2CO3 (66 mg, 0.48 mmol), diacetoxypalladium (1.8 mg, 0.0080 mmol), 6-methylpyridin-3-ylboronic acid (44 mg, 0.32 mmol) and sodium 2′-(dicyclohexylphosphino)-2,6-dimethoxybiphenyl-3-sulfonate (8.2 mg, 0.016 mmol). The reaction mixture was degassed with argon, sealed and heated to 80° C. for 5 hours. The reaction was cooled to ambient temperature and concentrated under reduced pressure. The residue was purified by silica gel chromatography (DCM/MeOH 10:1) to give the final product (20 mg, 34% yield). MS (apci) m/z=370.2 (M+H).
